The following parameters were assessed: radiation time, dose area product, air kerma reference point, pain severity during the puncture needle insertion, prosopalgia regression degree (according to visual analog scale) and the severity of facial numbness (according to the Barrow Neurological Institute scale) in the early postoperative period, and postpuncture complications.

Multidimensional Resonance Controlled by Critical Size in Printed Binary Colloidal Crystals for High-Contrast Imaging.

Colloidal crystal engineering enables the precise construction of structures with remarkable properties. However, the flexible and synergistic regulation of multiple properties of colloidal crystals remains a significant challenge. Here, we inspire from Brazilian opals to self-assemble polymer nanoparticles in the gaps of a single-layer opal substrate to fabricate large-scale binary colloidal crystals (BCCs).

A case of simultaneous bilateral pulmonary resection for arteriovenous pulmonary malformation.

Pulmonary arteriovenous malformation (PAVM) is a congenital vascular pathology, which is caused by the presence of a direct connection between the branches of the artery and the veins of the lungs, and the discharge of unoxygenated blood into the arterial bed. Arteriovenous malformations are characterized by a wide variety of clinical manifestations and, in some cases, may be accompanied with severe circulatory disorders.

Fabrication of high-density vertical CNT arrays using thin porous alumina template for biosensing applications.

This paper explores the process of forming arrays of vertically oriented carbon nanotubes (CNTs) localized on metal electrodes using thin porous anodic alumina (PAA) on a solid substrate. On a silicon substrate, a titanium film served as the electrode layer, and an aluminium film served as the base layer in the initial film structure. A PAA template was formed from the Al film using two-step electrochemical anodizing.

Time series is a data structure prevalent in a wide range of fields such as healthcare, finance and meteorology. It goes without saying that analyzing time series data holds the key to gaining insight into our day-to-day observations. Among the vast spectrum of time series analysis, time series classification offers the unique opportunity to classify the sequences into their respective categories for the sake of automated detection.

Pyrimido[5,4-]azolo[1,5-]pyrimidines and pyrimido[4,5-][1,2,4]triazolo[5,1-][1,2,4]triazines: multi-component synthesis and cytotoxic activity.

A multi-component method for the synthesis of pyrimido[5,4-]azolo[1,5-]pyrimidines and pyrimido[4,5-][1,2,4]triazolo[5,1-][1,2,4]triazines has been developed. It was shown that vicinal amino-nitrile and amino-ethoxycarbonyl derivatives of azolo[1,5-]pyrimidines and azolo[5,1-][1,2,4]triazines were converted to tricyclic heterocycles in the "AcOH-RC(OEt)-amine" system. Reaction conditions were optimized, patterns of this process were investigated, and intermediates were isolated.

Coupling between topological edge state and defect mode-based biosensor using phononic crystal.

A wealth of details regarding an individual's state of health, like a person's respiratory and metabolic functioning, can be studied by analyzing the volatile molecules and atoms in human exhaled breath. Besides, the salinity of seawater is a crucial factor in understanding its characteristics because any variation in the salinity of seawater represents the variations in the hydrological, biological, and chemical distributions. In this paper, a symmetrical one-dimensional phononic structure is theoretically designed using two symmetrical crystals separated with a defective cavity.

The daily data cover the period from January 1, 2015, to March 30, 2023, and were analyzed using two-dimensional sets of electricity and commodity prices.

Polariton lattices as binarized neuromorphic networks.

We introduce a novel neuromorphic network architecture based on a lattice of exciton-polariton condensates, intricately interconnected and energized through nonresonant optical pumping. The network employs a binary framework, where each neuron, facilitated by the spatial coherence of pairwise coupled condensates, performs binary operations. This coherence, emerging from the ballistic propagation of polaritons, ensures efficient, network-wide communication.

Composition, Structure, and Thermal Properties of Potassium Acetate Hydrates.

The crystal structure determines the properties of compounds and materials, although one can find simple yet industrially relevant compounds such as potassium acetate (KOAc) and its hydrates for which the properties and even the composition still remain misunderstood, owing to the lack of structural data. In this study, the crystal structures of KOAc polymorphs and hydrates were determined for the first time. The water content in the crystal hydrates was reliably determined revealing two new phases 3KOAc·2HO and KOAc·HO ( = 0.

Enhancement of stability and activity of zinc carbonate nanoparticles using chitosan, hydroxyethyl cellulose, methyl cellulose and hyaluronic acid for multifaceted applications in medicine.

Currently, biopolymer-based Zn-containing nanoforms are of great interest for medical applications. However, there is lack information on optimal synthesis parameters, reagents and stabilizing agent for production of zinc carbonate nanoparticles (ZnC-NPs). In this work, synthesis of ZnC-NPs was carried out by chemical precipitation with the use of chitosan, hydroxyethyl cellulose, methyl cellulose and hyaluronic acid as stabilizing agents.

Identification of novel phenolic inhibitors from traditional Chinese medicine against toxic α-synuclein aggregation via regulating phase separation.

Parkinson's disease (PD), a neurodegenerative disorder without cure, is characterized by the pathological aggregation of α-synuclein (α-Syn) in Lewy bodies. Classic deposition pathway and condensation pathway contribute to α-Syn aggregation, and liquid-liquid phase separation is the driving force for condensate formation, which subsequently undergo liquid-solid phase separation to form toxic fibrils. Traditional Chinese Medicine (TCM) has a long history in treating neurodegenerative disease, herein; we identified chemicals from herbs that inhibit α-Syn aggregation.

Whisker-free lithium electrodeposition by tuning electrode microstructure.

Growth of lithium whiskers or dendrites is the major obstacle towards safe and stable utilization of lithium metal anodes in rechargeable batteries. In this study, we look deeper into the mechanism of lithium electrodeposition. We find that before lithium whisker or dendrite nucleation occurs, lithium is deposited into the grain boundaries of the metal electrode, which we directly observed in the focused ion beam cross-sections of the lithium electrode.

Chimera states in a system of stationary and flying-through deterministic particles with an internal degree of freedom.

We consider the effect of the emergence of chimera states in a system of coexisting stationary and flying-through in potential particles with an internal degree of freedom determined by the phase. All particles tend to an equilibrium state with a small number of potential wells, which leads to the emergence of a stationary chimera. An increase in the number of potential wells leads to the emergence of particles flying-through along the medium, the phases of which form a moving chimera.
